Profiler View

The Profiler view helps you analyze the performance of your applications. You can easily monitor the calling frequency and execution time for procedures and functions. The Profiler view can be used with both command line and compiled programs.

To add the Profiler view to the current perspective, click Window → Show View → Profiler.

To analyze a program:

  1. Compile the program.

    2. Note
    All program modules must be compiled prior to profiling.

    For more involved programs, you can use RESOLVE_ALL to compile all uncompiled functions or procedures that are called in any already-compiled procedure or function.

  2. Click Enable Profiling on the Profiler view toolbar.
  3. Run the program.

    4. The Profiler report remains blank.

  4. Click Refresh Results to populate the report.
